2Introduction
The CO2 Sensor measures CO2levels in an agricultural environment. Working in conjunction with a
controller, the CO2 Sensor sends a signal when the measured CO2 levels fall outside the user-defined
specifications. This signal activates the controller’s ventilation. Refer to Figure 1.
Figure 1: CO2 Sensor
NOTE The unit comes supplied with a 12 VDC supply.
2.1 Features
•Self-contained environment and impact-resistant sealed box
•Quick open clasps
•Easy installation
•Simple to connect and configure
•Continuous uninterrupted CO2 sensing
•Diagnostic LEDs
•Door-mounted sensor

2.2 Operating Mode
The CO2 Sensor operates in a Current Loop mode (4 - 20 milliamps). In this mode, the CO2Sensor
provides a signal proportional to CO2levels.
NOTE Verify that J2 is not shorted (refer to Figure 2).
